Comments on: UCS Multihop FCoE In Under an Hour http://blogs.cisco.com/datacenter/ucs-multihop-fcoe-in-under-an-hour/ Tue, 21 May 2013 19:33:04 +0000 hourly 1 By: simon gordon http://blogs.cisco.com/datacenter/ucs-multihop-fcoe-in-under-an-hour/#comment-697797 simon gordon Thu, 03 Jan 2013 21:45:17 +0000 http://blogs.cisco.com/?p=92485#comment-697797 Thanks for the clarification both on capability and diagram. i miss read the picture because looking at the left i saw (bottom to top) ‘ve mode’ ‘npiv mode’ and ‘npv mode’. however i now see on the right the labelling of ‘fi’ ‘upstream fcf’ and ‘core fcf’.

just to nit pick, i think you intend to say ‘fcf with npiv enabled’ rather than ‘npiv switch’.

You raise an excellent point. This specific example is, in reality, a single-hop deployment as the FI is put into NPV mode and the upstream NPIV switch is the one connected via E-port to the core switch. That is, the Domain ID encompasses the FI, and there is only one ISL in this topology.

However, the option also exists to have the FI in FC-SW mode, connecting via VE_Port to the upstream switch, maintaining separate FCIDs and creating ISLs. From a configuration standpoint, it takes no more or less time to set up.

(put to side for a minute that a 2 fc switch or 2 fcf/fcoe-switch san would only be a single hop).

in this diagram and blog i only see reference to FCoE to FCoE N_Port-Virtualizer mode for the UCS switch and not the UCS switch acting as an FCF with a VE Port to the next hop FCF – or did i miss something ???

now, personally i agree that ALL hops matter equally whether FSB, NPV, or FCF.

I’m looking to integrate a FCoE SAN into the environment so this is very helpful.
